21.2 PCB Layout Example, Differential Connection to a Loop Antenna
Figure 37 shows a PCB layout example for the application schematic in Figure 36.
A double-sided FR-4 board of 1.6mm thickness is used. This PCB has a ground plane on
the bottom layer. Additionally, there are ground areas on the component side of the
board to ensure sufficient grounding of critical components. A large number of via holes
connect the top layer ground areas to the bottom layer ground plane. There is no ground
plane beneath the antenna.
No components in bottom layer
